Synergies

This pass lowers several high-end defensive and sustain payoffs while shifting Spore toward stronger Energy disruption at max stacks.

Spore

Reduced its self-healing, with max-stack Spore now burning more Energy but healing its lowest-health ally for less.

  • Self-heal at 2 / 3 Spore: 12% / 16% → 5% / 10% Max Health
  • Enemy Energy loss at 2 / 3 Spore: 12% / 16% → 10% / 20% of the caster’s Energy Cost
  • Lowest-health ally heal at 3 Spore: 8% → 5% of the caster’s Max Health

Bulwark

Reduced the Thorns granted to Bulwarks at the final threshold. Team Max Health bonuses are unchanged.

  • Thorns at 5 Bulwark: 1% → 0.5% of Max Health

Nature

Reduced the healing at the final two thresholds. Nature units continue to heal for twice the listed team amount.

  • Non-Nature healing at 6 Nature: 2.5% → 2% missing Health per second
  • Non-Nature healing at 8 Nature: 3% → 2.5% missing Health per second
  • Nature-unit healing at 6 Nature: 5% → 4% missing Health per second
  • Nature-unit healing at 8 Nature: 6% → 5% missing Health per second

Mystic

Reduced the permanent combat bonuses triggered when an ally first drops below 55% Health. The 3-Mystic allied-death effect is unchanged.

  • Damage Amplification and Damage Reduction at 2 / 3 Mystic: 7% / 12% → 5% / 10%

Granite

Shortened its Invulnerability and made the final-threshold retrigger less frequent.

  • Invulnerability at 2 / 3 Granite: 4s / 5s → 3s / 4s
  • 3-Granite Invulnerability retrigger: Every 20s → every 30s

Colossus

Reduced how frequently Colossus units Taunt nearby enemies. Taunt duration, range, and allied Damage Reduction are unchanged.

  • Taunt interval at 2 Colossus: 8s → 12s
  • Taunt interval at 3 Colossus: 6s → 8s

Enchanter

Reduced the Max Health healing triggered by Omega. Pure Damage and the final-threshold Damage Amplification remain unchanged.

  • Max Health healing at 2 / 3 Enchanter: 3% / 5% → 2% / 4%

Toxic

Reduced the Pure Damage dealt by its Vanquish explosions. Healing, Poison, and explosion radius are unchanged.

  • Explosion damage at 2 / 3 Toxic: 8% / 10% → 4% / 6% of the vanquished enemy’s Max Health

Shock

  • Lightning damage increased from 300 / 400 → 400 / 600 Energy Damage
  • Permanent Energy Resistance reduction per lightning increased from 2 → 3, still stacking up to 20 times.

Tempest

  • Dodge Chance granted to Tempest units increased from 20/30 → 20/40.

Forge & Legendary Augments

These changes reduce some of the strongest broad defensive and stat packages without changing their core effects.

Infusing Void Reactor

Reduced the Heal Efficiency granted to allies and the doubled amount gained by the holder after 10 seconds. Its Health and Omega Power stats are unchanged.

  • Allied Heal Efficiency: 15% → 10%
  • Holder Heal Efficiency after 10 seconds: 30% → 20%

Inner Limit Breaker

Reduced its Max Health bonus. Its 40 Resistances are unchanged.

  • Max Health: 45% → 40%

Radiating Impact Reactor

Reduced its direct stat bonuses. Its Burn and Poison effects are unchanged.

  • Attack Damage: 10% → 5%
  • Max Health: 6% → 3%

Radiating Impact Reactor

  • Max Health Pure Damage dealt on every attack increased from 1% → 2%.

Drone Augments

Drone-wide defensive and healing effects have been reduced across all three stages.

Defensive Upgrade

  • Resistances granted every 5 seconds at Stages I / II / III:
    3 / 5 / 7 → 2 / 4 / 6

Rejuvenating Pulse

  • Max Health restored every 4 seconds at Stages I / II / III:
    2% / 3% / 5% → 1% / 2% / 3%

Second Wind

  • Max Health restored after 10 seconds at Stages I / II / III:
    10% / 20% / 30% → 8% / 16% / 24%
